A not so common and local species in Belgium, well established in the southern provinces.
The larva lives on several deciduous trees, but especially on Alnus glutinosa and Betula. Hibernates as a pupa, burrowing into rotten wood. The adults come to light and sugar.
The adults fly in one generation a year from early May till early July.
